Coccidioides is a dimorphic fungus endemic to the southwestern US, northern Mexico, and focal areas in Central and South America (see Fig. 29-1). Disease is caused by two species: C. immitis, the organism responsible for coccidioidomycosis primarily in California, and C. posadasii, the organism responsible for disease primarily outside California Valley Fever (Coccidioidomycosis) Español (Spanish) Valley fever, also called coccidioidomycosis, is an infection caused by the fungus Coccidioides. The fungus is known to live in the soil in the southwestern United States and parts of Mexico and Central and South America. The fungus was also recently found in south-central Washington Unfortunately, Coccidioides, the fungus that causes Valley Fever, is not often detectable in respiratory specimens and diagnosis is thus often made by serology - avoiding more invasive means of obtaining a diagnosis. Below is a timeline outlining a 'typical' Valley Fever disease course Coccidioides immitis is a dimorphic fungus that exists in two distinct forms, saprophytic and parasitic. In the soil, the organism exists as a mold with septated hyphae resembling a shape of a barrel. When entering a host, the arthroconidia (spores) break off from the hyphae and evolve into round structures called spherules

Cough and fever are common symptoms of Valley fever. Many people who are exposed to the fungus Coccidioides never have symptoms. 1 Other people may have symptoms that go away on their own after weeks to months. If your symptoms last for more than a week, contact your healthcare provider. Symptoms of Valley fever include: Fatigue (tiredness) Cough Coccidioides immitis is a pathogenic fungus that resides in the soil in certain parts of the southwestern United States, northern Mexico, and a few other areas in the Western Hemisphere. Epidemiology. C. immitis, along with its relative C. posadasii, is most commonly seen in the desert. Valley fever is a fungal infection caused by coccidioides (kok-sid-e-OY-deze) organisms. It can cause signs and symptoms such as a fever, cough and tiredness. Two coccidioides fungi species cause valley fever. These fungi are commonly found in soil in specific regions Epidemiology. The most common forms of Coccidioides spp are Coccidioides immitis and Coccidioides posadasii 1.These species are endemic to many desert regions of North, Central and South America, especially in the American state of Arizona 1.The disease can occur in hosts with a well-functioning immune system, especially with repeated exposure, but the risk is increased if one is.

The detection of Coccidioides in any clinical specimen by culture or microscopy is the diagnostic standard, but these results are not instantly available, and obtaining samples can be problematic. Coccidioides species exist in two phases ( J Am Acad Dermatol 2006;55:929 ) Mycelial phase. Spherule phase. Mycelia are found in the soil and made of septate and ramified hyphae; as the environment dries, mycelia reproduce thick walled spores named arthroconidia. Infection occurs with inhalation or rare inoculation of arthroconidia Valley fever, also called coccidioidomycosis, is an infection in the lungs caused by a Coccidioides fungus that is usually found in the southwest United States, Central and South America, and Washington state. The condition is usually mild and gets better on its own, but some people with moderate to severe infections may need antifungal drugs. Coccidioidomycosis is a pulmonary or hematogenously spread disseminated disease caused by the fungi Coccidioides immitis and C. posadasii; it usually occurs as an acute benign asymptomatic or self-limited respiratory infection.The organism occasionally disseminates to cause focal lesions in other tissues For Coccidioides, immunodiffusion (ID) measures IgM antibody, while complement fixation (CF) measures both IgG and IgM.ELISA tests can be used to detect both coccidioidal IgG and IgM antibodies. While elevated single antibody titers may be diagnostic, paired specimens are preferred

Coccidioides spp. occur in the Western Hemisphere, at latitudes between 40ºN and 40ºS, from California to Argentina. The distribution of these organisms is patchy. They are endemic in the southwestern U.S., including Arizona (where the incidence in humans is particularly high), parts of New Mexico, Texas (west of El Paso), an Tricia Christensen Valley fever symptoms can include fever, headache, and tiredness. Valley fever results when people are infected with fungi called coccidioides, which is soil dwelling and present in arid areas, like parts of Texas, Arizona, and Nevada or in parts of Mexico and South America. Valley fever symptoms have up to three distinct stages, depending on the individual's vulnerability. Coccidioides species are known to be associated with infections caused by other fungi such as the yeasts Aspergillus and Penicillium species [7, 15, 14, 16]. The prevalence of Coccidioides species in the United States has been decreasing in recent years [7]. A. fumigatus is more common in the United States than in other countries (Figure 2) Coccidioides growth on an agar plate is a significant laboratory biosafety hazard because of the risk of inhalation of dislodged arthroconidia. When a specimen is sent for culture, laboratory personnel should be alerted to the possibility that Coccididoides spp. may be present,.

Abstract. Coccidioides immitis and C. posadasii are the causative agents of coccidioidomycosis, or San Joaquin Valley Fever. The disease was first described in 1892 in Argentina, and its distribution and frequency investigated into the mid-1900s. National reporting has measured a recent increase in disease burden in the United States Coccidioides species are dimorphic fungi within the Ascomycete division [].The two species that have been found to cause human disease are Coccidioides immitis and Coccidioides posadasii [2, 3]. C. immitis and C. posadasii are morphologically identical with no known phenotypic differences in pathogenicity. These fungi are commonly found in the environment, in the soil of hot and arid ecosystems Coccidioides may reactivate in such patients, leading to rapid development of severe pulmonary or disseminated disease. Such patients may present with a clinical picture of severe adult respiratory distress syndrome (ARDS), skin or bone involvement, meningitis, altered mental status due to obstructive hydrocephalus, or any combination of these Coccidioides immitis is a dimorphic fungus with a saprophytic (hyphal) phase that occurs in the soil and a parasitic form that occurs in the human host . The hyphal form proliferates during the rainy season and dies in the dry period, releasing highly infectious spores (anthroconidia) that become airborne because of wind, excavation, or farming Coccidioides immitis and C. posadasii are soil dwelling dimorphic fungi found in North and South America. Inhalation of aerosolized asexual conidia can result in asymptomatic, acute, or chronic respiratory infection. In the United States there are approximately 350,000 new infections per year. The Coccidioides genus is the only known fungal pathogen to make specialized parasitic spherules.
